Structure for the club head of a wooden club

ABSTRACT

An improved structure for the club head of a wooden club, characterized in that the inner lateral side of the ball impact face board of the club head is provided with a plurality of cylindrical bodies connected at one point and the cylindrical bodies are extended toward the lateral side of the club head such that the cylindrical bodies are focused at the center connection of the club head, and another one cylindrical body is extended from the center connection to the bottom edge of the rear board of the club head and is mounted. Thus, the ball-impact face board is provided with a strong compression, thereby allowing the swinging of the club to impact on a golf ball and the impact distance is greatly improved.

BACKGROUND OF THE INVENTION

[0001] 1. (a) Field of the Invention

[0002] The present invention relates to an improved structure for the club head, and in particular, a club head which improves the impact force on a golf ball.

[0003] 2. (b) Description of the Prior Art

[0004]FIG. 1 shows a conventional club head of a wooden shaft and the club head 1 is normally hollow. In order to produce long distance during impact with a golf ball, the club head is made into a bigger size, but, due to its hollow structure, the wind resistance during swinging cannot be controlled, as a result, the direction of ball-impact and distance cannot be controlled.

[0005] As shown in FIG. 2, the impact face board 11 of the club head during impact with a golf ball will cause a depression. The formation will affect the 15 impact force. In order to solve this drawback, titanium alloy or stainless steel is used for the making of the club head. However, the thickness of the club head will increase. FIG. 3 shows a wooden club head by having a ball impact face board 11 with a inner edge extended to a flat board 2. The flat board is connected to the long axle of the impact face board 11. As shown in FIG. 4, the flat board is extended at the rear lateral side to the lower edge of the rear board 12. The flat board 2 can increase the compression strength of the impact face board 11. However, in view of the above-mentioned design, the flat board 2 will increase the weight of the club head and it will not provide a long distance during impact with a golf ball.

[0006] Accordingly, it is an object of the present invention to provide an improve structure for the club head of a wooden club, which mitigates the above drawbacks.

SUMMARY OF THE INVENTION

[0007] Accordingly, it is an invention to provide an improve structure for the club head of a wooden club, wherein the inner lateral side of the ball impact face board is provided with a plurality of cylindrical bodies and one cylindrical body is extended to the bottom edge of the rear lateral side of the club head so as to enhance the strength of compression of the ball impact face board and in turn improve the objective of impact force of the club.

[0008] Yet another object of the present invention is to provide an improve structure for the club head of a wooden club, the top edge of the inner lateral side of the ball impact face board is provided with a rib, such that when the thickness of the impact face ball is reduced, the strength of the compression of the impact face ball is increased.

[0009] The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0017] For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, alterations and further modifications in the illustrated device, and further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

[0018] Referring to FIG. 5, there is shown an improved structure of the club head of a wooden club, wherein the inner lateral face of the ball impact face board 3 of a club head 3 is provided with a plurality of cylindrical bodies 41 respectively connected at one point at the impact region on the club head. In order to reduce the weight of the cylindrical bodies 41, the plurality of cylindrical bodies 41 are extended and connected at one connection point on the center of the club head, and an another cylindrical body 42 is extended to the bottom edge of the rear board 32 of the club head 32 and is mounted at the inner lateral face of the bottom edge. Next, the top edge of the inner lateral side of the ball-impact face board and the continuation region of the inner side of the top board 33 of the club head, a plurality of ribs 5 are spacingly mounted. The ribs 5 are extended from the impact face board 31 upward to the top board 33 and the rib 5 is an L-shaped structure. Thus, the strength of the ball-impact face board 31 is enhanced.

[0019] Referring to FIGS. 5 and 6, the cylindrical bodies 41 can be either in cylindrical shape or cornered cylindrical shaped body. The cylindrical body allows the impact face board, at the instance of impaction, to withstand the weight of the impact ball without bending. The material of the cylindrical bodies is metal, and the metal having a preferable strength but lighter is the best. This will improve the strength of the cylindrical bodies 41, 42 and the total weight of the cylindrical bodies is reduced. As shown in FIG. 5, the number of the cylindrical bodies 41 is preferable five, and one of the cylindrical bodies, 41 is connected at the center point of the impact face board and the other four bodies are respectively connected at the impact region. The connection point of the cylindrical bodies 41 is formed from a four point of the impact force. Besides, the compression of the ball-impact face board 31 is enhanced. In actual fact, two cylindrical bodies can be used, however, the strength and the weight factors have to complied with the above. As shown in FIG. 6, in order to upgrade the strength of the cylindrical bodies 41 and to control the total weight of the cylindrical body, the cylindrical body 41 and the other four bodies are extended to the rear side of the club head and are connected at the center of the club head. The cylindrical body is extended toward the rear side of the club head to form a cylindrical body 42 and is connected at the lower edge of the rear board 32. This will reduce the total weight of the cylindrical body and to reduce the center of gravity of the club head.

[0020] When the total weight of the club head is to be reduced and the club head has to be in a larger size, the thickness of the club head has to be reduced. In this case the compression strength of the impact face board 31 will become weaker and the connection strength of the top board 33 and the bottom board 34 is poor. As shown in FIG. 7, the connection edge of the bottom board 34 is relatively smaller and the effect will be lesser. The connection edge of the impact face board 31 and the top board 33 is provided with the L-shaped ribs 5, and as shown in FIG. 5, the ribs 5 are spacingly arranged.

[0021] In view of the above, the thickness of the impact portion of the club head is reduced and a plurality of cylindrical bodies 41, 42 and ribs are used to supplement the connection strength of the impact face board and the top board. The compression strength of the impact face board is improved. In accordance with the present invention, by the application of the cylindrical bodies and the ribs will increase the volume of the club head by reduce the center of gravity of the club head. This will increase of distance of impact of ball.

[0022] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0023] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
